An early build of SteamOS 3, intended for developers getting started with the Steam Deck, has leaked onto the internet. The interface of this OS will eventually replace the Big Picture Mode of the desktop client.
SteamDB foreman Pavel Djundik comes with a series of tweets about the leaked build. It is not known which developer has leaked the operating system to the internet. Valve opened up to devkit requests earlier this month. Djundik posts some screenshots of the interface running on a PC, but notes that there is nothing new in themselves: SteamOS 3’s interface has already been examined in several hands-on videos from gaming websites, such as that of IGN.
The image of the Linux-based SteamOS already runs on other handheld computers, according to Djundik. He does not name which these are, but it may concern devices such as the GPD Win 3, Aya Neo and OnexPlayer. Moderators on the SteamOS subreddit warn of the possibility of putting malware in the build and then spreading it further. Links to the build will be removed there as well.
